Patents by Inventor Kevin J. Chaput

Kevin J. Chaput has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Niobium alloys for high temperature, structural applications
    Patent number: 11846008
    Abstract: The present invention relates to Nb-based refractory alloys that are less expensive and less dense than current Nb-based refractory alloys, have better ductility than current Nb-based refractory alloys, yet which have similar or better high temperature strengths and oxidation resistance when compared to current Nb-based refractory alloys. Such Nb-based refractory alloys typically continue to be compatible with current coating systems for Nb-based refractory alloys. Such Nb-based refractory alloys are disclosed herein.
    Type: Grant
    Filed: January 4, 2022
    Date of Patent: December 19, 2023
    Assignee: United States of America as represented by Secretary of the Air Force
    Inventors: Kevin J. Chaput, Oleg N. Senkov, Todd M. Butler, Satish I Rao
  • Niobium alloys for high temperature, structural applications
    Patent number: 11198927
    Abstract: The present invention relates to Nb-based refractory alloys that are less expensive and less dense than some of the current Nb-based refractory alloys, have similar or better ductility, strength specific yield strength and oxidation resistance when compared to current Nb-based refractory alloys. Such Nb-based refractory alloys typically continue to be compatible with current coating systems for Nb-based refractory alloys. Such Nb-based refractory alloys are disclosed herein.
